Question about Blockscout

I have an archive node (erigon) and I am looking for similar capability to etherscan's getContractTransactions, getRegularTransactions, and getInternalTransactions. I am looking at blockscout, but if you have a better suggestion please give it. My questions are:

1) I assume the localhost server you set up will serve as an endpoint for the web based api queries on the blockscout website (like get contract txs, get internal txs, get transaction by hash, etc). Is this correct? And is there a way to directly query the locally created postgress database to get these same responses?

2) once indexing is done, does blockscout listen for new blocks and index them as they come in? It looks like blockscout just runs once from the tip of the chain to genesis.

thanks for any help you can provide.
